[Results of clinical and experimental studies in the diagnosis of periodontological function].

By means of clinical and experimental control studies in partly adjustable individual articulators, it was tested how exact an apparatus has to be in order to ensure a reliable clinical diagnosis of periodontal disease. In the clinical as well as the experimental part of the studies, it was possible to demonstrate that the intra-alveolar movement of the tooth plays the most important role in allfunctional disturbances of traumatized periodontal diseases.

[Endodontic-endosseal fixation and capping pin].

For improving the endodontic-endosteal fixation method, an endodontic-endosteal fixing and capping pin was developed after six years of experience. Its form and adaptability to the widened root canal permits succesful fixation via the canal in a single session with only little technical means. At the same time the pin with its cap enables permanent anchorage of the crown.

[Periodontal reaction to interdental osteotomy].

Interdental osteotomy presents a small risk for the tooth adjacent to the line of the osteotomy. Five out of 41 teeth adjacent to the site of an osteotomy showed loosening degree 1. The PM index rose from 1.0 to 1.4. The depth of the periodontal pockets did not change. The roots of two out of 41 teeth were damaged during osteotomy, but not devitalized.

[Periodontal conditions after surgery of maxillary sinus fistulas].

In 38 patients the periodontal conditions after closure of antrum perforations are examined. The following indices are used: plaque index, gingival index, degree of loosening, depth of pocket and index of osteolysis. As compared to the opposite side, significant atrophy of the bone is found in the region of the perforation. Otherwise no significant differences between the operated side and the non-operated side are observed.

[Periodontal conditions of the teeth next to the fracture line after stable plate osteosynthesis in the mandible].

Follow-ups in 21 patients with 30 fractures of the lower jaw which were treated with stable plate osteosynthesis showed that 94% of the teeth adjacent to the fracture line were not extracted. The rate of secondary healing was 7%. Evaluation of the periodontal conditions showed that only 14% of the teeth were not worth keeping and 45% of the teeth required treatment. It is pointed out that when treating mandibular fractures with stable plate osteosynthesis, retention of the teeth in the fracture line does not mean an increased risk as far as secondary healing and the tooth itself are concerned.

Clinical performance of esthetic posterior crowns in primary molars: a pilot study.

PURPOSE: The aim of this pilot study was to assess the clinical performance of esthetic crowns and to compare these to conventional stainless steel crowns (SSC). METHODS: Twenty two crowns (11 conventional and 11 esthetic) were placed in mandibular primary molars obeying the following criteria: the tooth was not mobile; no fistulae were present; the tooth had at least one caries free or properly restored antagonist and had to be in contact with one adjacent tooth mesially, in the case of the primary second molars or distally in the case of the primary first molars. Crown preparation was done in a conventional manner, but reduction was more extensive for the thicker esthetic crowns, to allow for proper occlusion. The crowns were evaluated clinically and radiographically after 6 months and the following parameters were assessed: gingival health, marginal extension, crown adequacy, proper position or occlusion, proximal contact, chipping of the facing (for esthetic crowns) and cement removal. RESULTS: At the 6 month evaluation all esthetic crowns were intact, without chipping of the facing, and no excess of cement was observed in both groups. No difference was found for marginal extension, occlusion, proximal contact, crown adequacy, and bone resorption, but a significant difference was found for periodontal health between esthetic crowns and conventional SSC (P < 0.001 McNemar test). CONCLUSIONS: The esthetic crowns assessed had several inconveniences, as they resulted in poor gingival health, are very expensive, and, although not measured, are bulky and without a natural appearance.

Tooth-implant and implant supported fixed partial dentures: a 10-year report.

PURPOSE: The use of implants for prosthetic rehabilitation of partially edentulous patients is increasing. However, the possibilities of placing implants in the posterior part of the mandible are often limited. The purpose of this longitudinal study with 10 years of follow-up was to evaluate the use of short implants supporting fixed partial dentures (FPD) in the posterior part of the mandible, and to compare implant supported FPDs to tooth-implant supported FPDs. MATERIALS AND METHODS: The patient material comprised 23 patients with residual mandibular anterior teeth, and each patient received FPDs unilaterally. On one side the FPD was supported by two implants, and on the other side by one implant and one tooth, thus permitting intraindividual comparison. The distribution of the two types of FPDs in each jaw was randomized. Implant success rates, marginal bone changes, and mechanical complications were studied. RESULTS: The tooth-implant connection did not demonstrate any negative influences on the overall success rates for the 10-year period, nor were the shorter implants found to be less favorable. CONCLUSION: It is suggested that a prosthetic construction supported by both a tooth and an implant may be recommended as a predictable and reliable treatment alternative in the posterior mandible.

Mechanical stabilization in the mandibular anterior segment.

Teeth in the mandibular anterior region of the mouth, affected by years of periodontal disease and resultant bone loss, frequently require treatment for the patient to be able to chew comfortably and effectively. Often patients choose to keep compromised teeth, despite being presented with treatment options involving a fixed or removable prosthesis. In these situations, mechanical stabilization becomes necessary. Current treatment possibilities include bonding with resin composite or placement of a bonded metal mesh splint, a cast metal resin-bonded retainer, or a fiber-reinforced resin composite splint. Coupled with good oral hygiene practices, these mechanical stabilization techniques can provide increased oral comfort and improved function, especially for geriatric dental patients.

Management of sports-related crown fractures.

Uncomplicated tooth crown fractures are the most common sports-related mouth injury and can have an excellent outcome if treated appropriately. Many times, however, crown fractures occur at the same time as concussion, luxation, displacement, or even avulsion injuries. This article discusses the treatment for and management of tooth crown fractures from sports-related injuries.
